Explanation:

Dietary protein will not be digested if Hcl were not being produced in sufficient quantities.

In the stomach, there are some glands found on the stomach lining that helps to release hydrochloric acid (HCl). Their major role is to dissolve food and produce an acidic medium.

The acidic media promotes and improves the conversion of pepsinogen to pepsin. Pepsin acts as an enzyme that supports protein digestion.

Protein digestion requires a pH of around 1.8 which can be achieved by the secretion of HCl.

As a result, if HCI is not released in the stomach in sufficient quantities, pepsin will not be activated and it would have a detrimental impact on protein digestion.

Therefore, we can conclude that dietary protein will not be digested if Hcl were not being produced in sufficient quantities.

Color is an example of an intensive physical property. Details about intensive physical property can be found below.

Intensive properties are physical properties that does not depend on the mass of the substance or system.

Another property of substances is the extensive property, which is the property that is dependent on the quantity of the substance.

I think it would be the beach because all the waves and such but in a pool with more people there is a tight space so they cant move around as much and as freely. But this could be a trickster question but I would choose the beach.

Hope this is right :)

Answer:

They all have the same density

Explanation:

Density is an intensive physical property, meaning that as long as the chemical formula is the same, that specific intensive physical property will be the same. For example. One kilogram of feathers has the same mass as one kilogram of bricks. Why? They both have a mass of one kilogram.

It's the same thing here. Since all the objects are (assumed to be) made up of 100% gold, they would all have the same density regardless of the mass. For extra points, say the density of each object is [tex]19 \frac{g}{cm^3}[/tex].

Answer:

Explanation:

The object with greater mass is having greater kinetic energy. Here, all the objects has the same velocity therefore, the bicycle is having least kinetic energy.

Kinetic energy is a form of energy generated by virtue of the motion of the object. The kinetic energy is related to the mass and velocity of the body by the expression below:

KE = 1/2 mv².

As per this equation, kinetic energy increases with an increase in mass or/ and velocity. The substance with greater mass is possessing the greater kinetic energy.

A dump truck has greater mass than a car and bicycle. Thus, at the same velocity for all, the greater kinetic energy is for the truck and the least kinetic energy is for the bicycle having the least mass here. Thus, option A is true.

Explanation:

Since we are starting from the number of atoms of Sulfur, we need to know two sets of formulas:

        ⇒ mass = (atoms ÷ Avogadro's Number) ×  molar mass

  mass = [(2.01 × 10²⁴ atoms) ÷ (6.022 × 10²³ atoms/mole)] × (32.06 g/mol)  

            = 107.01 g

The molar mass of sulfur S is 32.06 g/mol, then the mass in grams of a sample of S containing 2.01x10^24 atoms  is 107.01 g

The molar mass can be defined as the weight of one sample mole, by Multiplying  the subscript means  the number of atoms times that element’s atomic mass and add the masses of all the elements in the molecule to obtain the molecular mass.

Molar mass is  expressed in either gram ( g) or kilograms (kg).

Mass  = moles × molar mass

moles = atoms ÷ Avogadro's Number

       ⇒ mass = (atoms ÷ Avogadro's Number) ×  molar mass

 mass = [(2.01 × 10²⁴ atoms) ÷ (6.022 × 10²³ atoms/mole)] × (32.06 g/mol)  

          = 107.01 g

Answer:

A substance that neutralizes an acid is generally called a base and the basic substances that are soluble in water and alkali and the properties of alkalis are due to these hydroxide ions(OH−). ... - Thus, conclusively it can be said that all alkalis are bases but all bases are not alkali.

Answer:

This is false

Explanation:

it is actually the opposite, all bases don't dissolve in water, but alkali is a base that does dissolve in water. So, alkalis are bases, but not all bases are alkalis
